7. Tachysoma humicola humicola Gellért, 1957 View in CoL
( Fig. 2A)
Diagnosis. Body size approximate 30 × 15 μm in protargol preparations; body shape ellipsoidal, flattened dorsoventrally, both body ends rounded. Nuclear apparatus composed of 2 macronuclear nodules with a single micronucleus at left mid-body; micronucleus located between macronuclear nodules. Cytoplasm colourless. Movement, without any peculiarities, crawling on soil surface. Cirri composed of 18 cirri on average, as is typical in oxytrichids.
Remarks. Tachysoma humicola consists of two subspecies, Tachysoma . humicola humicola and T. humicola longisetum , which could be distinguished by the length of the posterior-most dorsal cilia (2-3 μm in T. humicola humicola vs. approximate 10 μm in T. humicola longisetum ; Berger, 1999). Of the Tachysoma species, Shin and Kim (1993a) reported T. pellionellum in Korea. Voucher slides. Two slides, including protargol-impregnated specimens (TB6), were deposited at the National Institute of Biological Resources in Korea (NIBR PR0000107205, NIBRPR0000107206).
